It also allows us to minimize communications latency between RSUs and connected vehicles, which are interested in massive multimedia contents. This work proposes novel proactive caching schemes at RSUs for the city mobility environment. We adopt the Manhattan city model, where streets are arranged in an organized manner and movable nodes are allowed to traverse along the grid of horizontal and vertical streets. Exploiting the information about vehicles demand and mobility patterns increases the caching capability and enables us to proactively cache desired files before its actual demand. The main objective of this work is to study how to minimize the communication latency for vehicles to receive their desired data items. We study non-clustered caching scheme where the optimization problem is formulated to find an optimal caching decision at each RSU. We extend our work by considering clustered caching scheme where RSUs in each cluster cooperate together to serve connected vehicles with minimum latency. Due to the complexity of these problems, we propose a sub-optimal caching policy for each scheme. We compare the performance of the optimal caching policy to that of the sub-optimal caching policy. Numerical results reveal that proactive caching has a great performance gain when compared to the reactive baseline scheme. Furthermore, results manifest that the clustered caching scheme has a significant performance over the non-clustered scheme.","PeriodicalId":121352,"journal":{"name":"2019 IEEE Wireless Communications and Networking Conference Workshop (WCNCW)","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122617087","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Amidst this, the issues such as coverage and affordability are likely to persist which will widen the rural-urban divide even further. The connectivity needs of rural areas call for an affordable broadband network which can be accomplished if we design a low mobility energy-efficient network. We refer to such a network as the Frugal 5G network. Deployment of Wireless Local Area Network (WLAN) Access Points (APs) is a cost-effective method to provide high-speed low mobility coverage to rural areas. Backhauling the WLAN APs is a challenging task as fiber backhaul is generally unavailable in rural areas. We suggest a method to design the wireless backhaul network in order to serve the WLAN APs. The design objective is to maximize system performance with respect to network throughput and delay while reducing infrastructure utilization. We propose a backhaul design method based on Simulated Annealing (SA) to achieve our objective. Our analysis shows that the proposed algorithm enhances the backhaul network throughput by 24% while minimizing the infrastructure used.","PeriodicalId":121352,"journal":{"name":"2019 IEEE Wireless Communications and Networking Conference Workshop (WCNCW)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129661091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their application areas range from communication to infotainment and medical to gaming. Inclusion of large number of features make availability of sufficient power for long operational hours a key challenge in these devices. Hence, limited battery life of wireless terminals makes energy efficiency an important issue in wireless networks. Medium access control (MAC) protocols play an essential role in this context. In fact, MAC protocols can have a significant impact on energy consumption since both transmission and reception activities are very costly in terms of energy. A centralised polling based MAC avoids collisions and can guarantee a higher energy efficiency with respect to pure carrier sense multiple access (CSMA). Pointer controlled slot allocation and resynchronisation (PCSAR) protocol implements power conscious scheduling techniques to enable terminals enter prolonged sleep state, thereby improving the overall energy consumption of the network. This paper investigates the performance of PCSAR and compares it with the IEEE 802.11 standard infrastructure power save mode (PSM). Results demonstrate that PCSAR outperforms the standard mode in a composite rate WLAN scenario. Moreover, use of TDM based circuit switching makes PCSAR more reliable. These features make it a potentially good candidate for energy efficient reliable low latency communication for current (4G/LTE) and future (5G and beyond) applications.","PeriodicalId":121352,"journal":{"name":"2019 IEEE Wireless Communications and Networking Conference Workshop (WCNCW)","volume":"32 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131003488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In these kinds of systems, it is assumed that multiple small cells with different operators share the same frequency band, hence it is necessary to arrange the small cells as densely as possible with avoiding co-channel interference. However, as the density of small cells increases, the degradation of communication quality due to inter-cell interference becomes a crucial issue. It is well known that highly accurate radio environment recognition can improve the spectrum sharing performance and measurement-based spectrum database (MSD) attracts attention for realizing the recognition. In this paper, we propose a method to increase the density of small cells while satisfying communication quality in multiple small cells jointly working with the MSD. The proposed method estimates the probability distribution of signal power-to-interference plus noise power ratio (SINR) by using the MSD. Based on the estimated probability distribution, the interference power control that satisfies the permissible outage probability of spectrum shared system is performed, maximizes the number of small cells that can share the spectrums.","PeriodicalId":121352,"journal":{"name":"2019 IEEE Wireless Communications and Networking Conference Workshop (WCNCW)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122788021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A network platform with use case and service dedicated slicing is designed on the fundamental principles of ETSI compliant NFV Management and Network Orchestration (MANO) framework. The slicing is done primarily on the Core Networks (CN) with evolved packet core and ip multimedia subsystem functionalities in different slices. The virtual network function instances are instantiated in OpenStack and VMWare cloud environments using an NFV Orchestrator. The virtual instances and the required resources can be instantiated, terminated and scaled in a slice according to the requirements of the end user and nature of the use case. Focusing on different service demands, the paper demonstrates three test cases utilizing different slices from the components in the CN for each case. It also provides an overview on radio spectrum sharing possibility between two operators on a specified service level agreement with each operator having own CN infrastructure.","PeriodicalId":121352,"journal":{"name":"2019 IEEE Wireless Communications and Networking Conference Workshop (WCNCW)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132683408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
